I get two things from this news. First: police the use of your APIs, they are often the soft underbelly of your applications; second: watch out for large numbers of follow/unfollow actions on twitter. I’ve stopped automatically following-back on my twitter accounts…:
ManageFlitter, Statusbrew, and Crowdfire have had their access to the Twitter API revoked for allegedly helping users abuse the service, aggressively and repeatedly following and unfollowing large numbers of other accounts. This is a tactic frequently employed by Twitter spammers.
Twitter reserves the right to rate limit, suspend, or terminate developers’ access to its API if it believes they have violated its automation rules.
As TechCrunch describes, the three apps attempt to boost the number of Twitter followers an account has by automatically following a large number, waiting a few days, and then unfollowing any who do no return the favour by following back. Accounts wishing to use such a service typically pay a monthly fee.
